|Mozart Visualizations K.545 for classroom teachers - Matthew D. Thibeault|
These files present multiple views of Mozart's famous K.545 sonata. All are designed to be printed out for classroom use in the following way: print, cut, tape together, then laminate. In this way, students can easily mark the score as they listen, coming up with theories about music, noticing aspects that interest them, etc. Most of the views combine Western score notation, MIDI piano roll, an amplitude display, and a spectrogram...

|Visualization of John Philip Sousa's Invincible Eagle - Matthew D. Thibeault|
John Philip Sousaâs (1854-1932) marches have been an embodiment of patriotism for Americans since the late 19th century. Dedicated to the Pan-American Exposition held in Buffalo, New York during 1901, Invincible Eagle is considered to be one of Sousaâs best marches. Three different representations allow students to examine and explore the music. The top visualization presents a MIDI piano roll of the notes; the center version presents a spectrogram that depicts the overtone series, as well as ...

|Marathi Isolated Word Recognition System using MFCC and DTW Features|
This paper presents a Marathi database and isolated Word recognition system based on Mel-frequency cepstral coefficient (MFCC), and Distance Time Warping (DTW) as features. For the extraction of the feature, Marathi speech database has been designed by using the Computerized Speech Lab. The database consists of the Marathi vowels, isolated words starting with each vowels and simple Marathi sentences...

An adaptive filter is a filter that self-adjusts its transfer function according to anoptimization algorithm driven by an error signal. Adaptive filter finds its essence inapplications such as echo cancellation, noise cancellation, system identification and manyothers. This paper briefly discusses LMS, NLMS and RLS adaptive filter algorithms forecho cancellation. For the analysis, an acoustic echo canceller is built using LMS, NLMSand RLS algorithms and the echo cancelled samples are studied usi...

|Visualization of Vibrato as Phonograph Effect - Matthew D. Thibeault|
In his book Capturing Sound, Mark Katz explores changes in violin vibrato over time as a "phonograph effect". He presents three violin recordings of Brahms' Hungarian Dance No. 1 recorded between 1903 and 1940. Below, the first twenty-four measures of each recording are visualized using a spectrogram that depicts time (left to right), pitch (low to high from 0-4000Hz), and volume (soft blue to medium red to loud yellow)...
